FOLDER FOR FORMING A SLIDE Filed Oct. 1929 L 1 INVENTOR M10 AJVmqy; it5:3; BY ('5 /[I' ATTORNEY Patented June 13, 1933 UNITED STATES PATENTOFFICE IBEDEBIO A. IORNY, 01 NEW YORK, N. Y., ASSIGNOR TO NEWS.PROJ'ECTION CORPO- BATION, OF NEW YORK, N. Y., A CORPORATION 01 NW YORKFQLIDEB FOR FORMING A SLIDE Application filed October 1, 1929. fierialNo. 396,465.

This invention relates to supports for cellophane, and has for an objectthe provision of a support for cellophane or the like to facilitatesupporting such cellophane or the like in a typewriter while typewritingupon the same.

It is still a further object of the present invention to provide afolder or support for cello hane or the like whereby the cellophane canbe readily inserted in a typewriter, a record be accurately positionedon such cellophane, and the cellophane then be readily removed from suchsupport to be used in a projection machine slide.

In stock brokers offices and tht like, it has become desirable to flashupon a screen from time to time during the day news items which mightaffect the market. For this purpose it has been found desirable toproduce a slide with a printed record thereon to be inserted in theprojecting machine generally known as delineascope or the like. Sincethese'records of news items are only of value if flashed to the customerin time to anticipate the market change, if any, various screens havebeen resorted to rapidly to produce a rinted record on a slide.Considerable difculty has been encountered, however, rapidly to producea printed record at low cost.

To this end the present invention also aims to provide an improvedfolder for producing a slide which folder is adapted to receive a sheetof cellophane or other transparent material, the folder so supplied theninserted in a typewriter, a record printed on the transparent sheet, thetransparent sheet then removed from the folder and thereupon insertedbetween two hinged sheets of glass to form a slide.

These and other features, capabilities and advantages of the inventionwill appear from the subjoined detail description of one specificembodiment thereof, illustrated in the ac- 45 companying drawing inwhich Figure 1 is a perspective of a folder in open position;

Fig. 2 is a perspective of a sheet of cellophane;

Fig. 3 is a perspective of the folder with the sheet of cellophaneformed therein;

Fig. 4 is an elevation of the sheet of celloph ane after the message hasbeen formed thereon;

Fig. 5 is a perspective of two sheets of glass hinged to one another inopen position Fig. 6 is an elevation of the sheets of hinged pieces ofglass and the sheet of cellophane disposed therein;

Fig. 7 is a side elevation of the projecting machine and a screen insection adapted for use with the present invention; and

Fig. 8 is a side elevation of another type of projecting machine andscreen in section adapted for use with the present invention.

For the recording of a message, a sheet of papers is provided having arear section 1 and a front section 2 provided with a window 3 cut in thefront section 2, the sheet S being folded alon the edge 4 to form thesections 1 and 2. from the edge 5 .of the window 3 so as to form aborder 6 adjacent the ed e 4. The other three edges 7, 8 and 9 of t ewindow 3 are similarly spaced from the edges of the section 2 to formborders around the window 3. The window 3 is considerably smaller inwidth and length as compared to the width and length of the cellophanesheet C.

.When forming a message on the cellophane sheet C, the same is insertedbetween the sections 1 and 2 of the paper sheet S, as illustrated inFig. 3, and then inserted in a typewriter in the usual way, making surethat the edge 10 of the cellophane sheet U rests snugly against theinner face of the edge 4 of the paper sheet S before inserting suchfolder S and cellophane sheet C in the typewriter. Thereupon the messageis printed across the he edge 4 is sufiiciently spaced vided with aborder 13 around the edge thereof, as indicated in Fig. 5. The twosheets are secured to one another by a hinge 14 consisting of a gummedpiece of cloth or the like.

After the cellophane sheet C is inserted between the sheets of glass 11and 12 with the message registering within the border 13 as illustratedin Fig. 5, here also making sure that the edge 10 of the cellophanesheet C rests snugl against the inner face of the. hinge mem er 14:,proper registration is produced. It is of course understood that thepaper sheet S and border around the opening 3 1s cut to correspond tothe window 15 formed within the border 13 of the glass folder G, andthat the width of the border portion 16 corresponds to the width of theborder 6 of the paper sheet S so that proper registration of the messageon the cellophane sheet C will be produced when the cellophane sheet Cis transferred from the paper folder S to the glass folder G.

When the slide is produced, as illustrated in Fig. 6, consisting of thecellophane sheet C located between the glass sheets 11 and 12 of thefolder G, the same is ready for insertion in the slide carrier 17 of theprojecting machine P illustrated in Fig. 7. In the embodimentillustrated in Fi 7, straight projection is produced, the lig t raysfrom the lamp 18 passing through the condenser 19 to the slide supportedin the slide carrier 17 and then passing through the objective lens 20to the screen 21.

In the embodiment illustrated in Fig. 8, a mirror 22 is interposedbetween the condenser 23 there illustrated and the slide carrier 24there illustrated from which the light rays pass through the objectivelens 25 to the mirror 26 and then to the screen 27.

Preferably the free ed e of the rear section 1 of the sheet of paper isprovided with a flange 28 to serve as an anchoring stop for thecellophane sheet C when the sheet C and mask formed by the sheet ofpaper S is fed through the typewriter.

It is obvious that various changes and modifications may be made to thedetails of construction without departing from the general spirit of theinvention as set forth in the appended claims.

I claim:

1. A paper folder for'supporting a trans parent sheet in a typewriterwhile producing a message on the same to be used in a slide, said paperfolder when folded corresponding in area to the area of the folded slidefolder for which the transparent sheet is to be produced and foldedalong two parallel lines to form two main co-extensive sections and anarrow flange section, one of said main sections having a window formedtherein with a border, the other of said main sections forming abacking, the flange section being formed at the free end of the backingsection and forming a positioning stop for the transparent sheet beforethe window forming section is folded over on to the backing section, theprinted matter on said sheet being readable parallel to the folds ofsaid folder so that the folds of said folder will extend axially withthe platen of the typewriter during printing and no folds extendtransversely to the axis of the platen.

2. A rectangular paper folder for supporting a transparent sheet in atypewriter while producing a message on the same to be used in a glassslide folder having an opaque border around the edge thereof to form awindow therebetween, said paper folder being creased along two parallellines to form when folded a package in area corresponding to the area ofthe slide folder when folded, the two creases dividing the folder intotwo main co-extensive rectangular sections and one narrow flange sectionextending the full width of the folder, one of said main sections havinga window formed therein within a border, the window in said main sectionin area corresponding to the area of the window in the slide folder, theother of said main sections forming a backing, the flange section beingformed at the free end of the backing section and forming a positioningstop for the transparent sheet before the window forming section isfolded over on to the backing section, the printed matter on said sheetbeing readable parallel to the folds of said folder so that the folds ofsaid folder will extend axially with the platen of the typewriter duringprinting and no folds extend transversely to the axis of the platen.

3. A rectangular pa r folder for supporting a transparent s eet in atypewriter or the like while producing a message on the same to be usedin a slide, said paper folder being formed by being creased along twoparallel lines to form when folded a ackage in area corresponding to thearea 0 the slide, the two creases dividing the folder into two mainco-extensive rectangular sections and a narrow flange section extendingthe full width of the folder, one of said main sections having two freelateral edges, one free end edge, a window surrounded by a border, andone end edge common to the other main section, the other main sectionhaving one end edge common to said first main section, two free lateraledges and its other end edge com- HQI; to said flange section, and saidflange section having one end edge common to said second main section,two free lateral edges and one free end edge, the flange section whenfolded being folded between the two 'main sections upon the transparentsheet to be supported, the printed matter on said sheet being readableparallel to the folds of said folder so that the folds of said folderwill extend axially with the platen of the typewriter during printingand no folds extend transversely to the axis of the platen.
